Biography
al-Muwahhid Taqi al-Din was born in 1241 to the Ayyubids, a dynasty of Sunni Muslim Levantines. His father was al-Muazzam Turanshah, the Sultan of the Ayyubid Caliphate from 1249 to 1250, who was murdered by a group of angry Mamelukes under Baibars at the end of his reign. al-Muwahhid Taqi al-Din became a prince of Egypt, albeit of a different line than the reigning Sultan Qutuz, who was a non-Levantine Mamluk. al-Muwahhid Taqi al-Din reigned over the city of Edessa (present-day Sanliurfa, Turkey) as its high chief under the Qutuzid Sultanate, and he lived lavishly, having four wives. In 1261, Hulegu Khan's Ilkhanate conquered Syria and al-Muwahhid Taqi al-Din became a vassal of the Mongols.

Life under Hulegu Khan made al-Muwahhid Taqi al-Din hostile, as he was opposed to the Tengri pagan (later Orthodox Christian) ruler and his Christianization of the empire. He became a dangerous faction leader against Hulegu Khan, so Hulegu began a plot against his life, involving several loyal Mongol courtiers plotting his doom.
